UNITED STATES PATENT OFFICE 5Claims.

.My invention relates to shoe making 'and a principal object of myinvention is to provide an improved and simplified method of makingshoes of the type originally taught in my United ,5 States Patent No.1,569,823, wherein an insole, to which the upper is afxed, includes anintegral heel portion, a shank portion and a ball portion having acentral opening therein dening a continuous marginal rand extending fromthe front of one side of the shank around the toe and to the front ofthe opposite side of the shank to afford means for initially alxing the.upper to the insole, land an outsole is provided having a marginaldepression conforming to the rand for receiving the same with the upperattached thereto, whereby the central portion of the inner face of theoutsole is disposed flush with the upper surface of the rand. g

Referring to the drawings:

Figure 1 is a plan view of the female portion of a die employed tocentrally depress the ball portion of the rounded sole which is shownlying thereon.

Figure 2 is a cross sectional view taken on 25 lines 2-'2 of Figure 1and illustrates, on a larger scale, the ball portion of the soledepressed between the male and female die portions.

.Figure 3 is a longitudinal sectional view illustrating the method bywhich the rounded sole is split to provide the complementaryV outsoleand insole portions.

Figure 4 is a longitudinal section thru the insole portion.

Figure 5 is a longitudinal section thru the outsole portion.

Figure 6 is a longitudinal section thru the backing piece employed tosupport and reinforce the sole during the splitting operationillustrated in Figure 3.

Figure 7 is an inverted plan view of the insole with the upper lastedand secured thereto.

- Figure 8 is a longitudinal sectiontaken thru the insole and portionsof the attached upper.

VFigure 9 is a longitudinal section illustrating the ball tread portionvo1! the shoe with the outsole assembled thereto, and

Figure 10 is a side elevation of a completed shoe, shown partly insection to reveal the nished relationship of the sole portions.

In carrying out my present invention I rst provide a full rounded sole30 and then inex or depress-the central ball tread portion thereof adistance somewhatgreater than the thickness of an insole .to be removedtherefrom; This I accomplish by pressing the sole between the male andfemale elements, 33 and 34 respectively, of a swage or pressing die, asillustrated in Figure '7.

After removal from the pressing die, the sole Ais reenforced by aperforate backing strip 36 (see Figure' 6), which is formed tocomplement the depressed portion of the sole and-is lpreferably made ofa durable and somewhat exible compoo sition material. then passedbetween the rollers 37-37- of a conventional leather splitting machine,the splitting blade 38 of which is positioned to cut above the bottom ofthe depressed area 35, so that when the sole has been split its fulllength, an insole portion 39, perforate centrally of its ball treadportion, and an outsole portion 40, is provided. The insole 39, formedas above and trimmed to; proper size, comprises an integral heelportion, a shank portion-and a ball portion, the said ball portionhaving a central opening therein defining a continuous marginal rand 39lextending from the front of one side of the shank around the toe,

The sole thus backed up, is 1 and tothe front of the opposite side vofthe The insole 39 is next lasted to the upper .42 of" the shoe to whichit is secured by any of such special adhesives as are `well-known inthis art, or by other suitable means, preliminary to which `a patch. 43may be removably pasted to cover the perforate portion of the insole. /J

The outsole 40 is then placed inposition over the lasted insole and thedepressed portion.35 thereof is forced back intoits original normalcondition, as illustrated in Figure 9. In this manner a marginaldepression 40' is dened on th'e inner side of the outsole which conformsto the rand 39 and receivesthe same with the upper attached thereto,whereby the central portion posed flush with the upper surface' of therand.

The remaining steps necessary-to'complete the. shoe are the usual onesconsisting in removing 35 of the inner face of the outsole is dis- 40the patch 43, assembling the sole lining and 45 other outsole from`which a similarV insole has.,

l been split.

A the foregoing considered merely illustrative of my invention as denedin the here appended claims: f

I claim:

1. In shoe 'making methods, that improvement which includes rounding vafull sole from suitable material and depressing a central area of theball portion thereof, then splitting the sole above the depressed'areato obtain an insole therefrom, lasting a shoe upper to the insole insecured relation, replacing the sole in its original relation to theinsole and restoring it to its normal undepressed condition; theout,solethus provided having a ball portion centrally elevated in thicknessandthe insole thus'obtained having an opening in the ball portionthereof to receive the elevated portion of the outsole.

2. In shoe makingmethods, that improvement which'includes rounding afull sole from suitable material; temporarily depressing a central area'of the ball portion thereof; then, while the sole is thus depressed,continuously splitting the sole above the depressed area toI obtain aperforate insole therefrom; lasting a shoe upper to the in- I sole insecuredJelation, and replacing said sole l vin its original relation tothe insole and securing v it thereto.

' blank from vsuitable material; temporarily depressing the blank'over acentral area of the ball portion thereof; then, while the blank is thusdepressed, f continuously splitting the blank above the depressed areato remove therefrom a full insole having an opening therein defining acontinuous marginal rand, said rand extending from the iront of'one sideof the shank around the toe to the front of the opposite side of theshank vancl aii'ording means for ,amxing an up'per to the insole, andthe Aremaining 'part of said blank comprising an outsole unreduced inthickness over an areacomplemental to the opening in the insole. 4

4. In shoe making methods, that improvement which includes roundingl afull sole from suitable material and depressing a central area of theball portion thereof, then splitting the soleabove the depressed areato. obtain a perforate insole therefrom, lasting a shoe upper to theinsole in secured relation, replacing the sole inits original relationto theinsole and securing it thereto, and restoring the sole to itsnormal undepressed condition.

5. In shoe making methods, that improvement which. includes rounding afull sole from vsuitable material; temporarily depressing `a centralarea of the ball portion thereof; then, while the sole is thusdepressed; continuously splitting the sole above the depressed area toprovide an outsole having a ball portion centrally elevated in thicknessand an insole having an opening in the ball portion'thereof complementalto said outsole elevation; lasting a shoe upper to the insole in securedrelation; and securing an outsole thus formed to said insole and to theoverlasted portions of the upper.
